ToiafZZ whom it mwyconcerm Be it known that I, CARL RsTEL, engineer, asubject of the Emperor of Germany, residing at Magdeburg-Buckau,Prussia, have invented certain new and useful Improvements in BreechLoading Fire Arms, of which the following is a specification, the samehaving been patented to me in Germany, No. 41,0017, dated January 13,1887 ;4 in Austria-Hungary, to Vol.37, XXI, page1,120 1,100, dated June10, 1887; in Belgium, No. 77,993, dated June 28, 1887, and in Italy,XXI/43, No. 21,980/360, dated September 30, 1887.

My invention relates to the charging and I5 cooking mechanism of breech-loading tirearms; and it consists of certain details of construction,hereinafter fully described, and pointed ont in the claims.

In the drawings which accompany and form 2o part of this specification,Figure I is an axial sectional view of the breech of a gun having myimprovements applied thereto. Fig. Il is a sectional view with thebreech iblock removed. Fig. III is a sectional view in a plane at rightangles to that of Fig. I. Fig. IV is a view similar to Fig. I, thebreech-block, however, being here shown down and the firingpin being incocked position. Fig.V is a sectional view with breechblock inelevation. 5o FigVI'is aside elevation of the breech-block, theoperating mechanism being removed. Fig. VII is an axial section of thesame ou the line x y, Fig. VI.

1 represents the barrel of the gun, and 2 the breech-block, guided inthe breech by means of tongues 3v and grooves 4, slightly slanted withreference to the axis of the gun-barrel, so that as it descends thebreech-block will slight-ly recede from' and as it ascends will appreachclose to the rear end of the barrel.

5 is a groove on the breech-block with which a screw-stud, 6, on thebreech engages to limit the play of the breech-block. The latter israised and lowered by the crank 7, Fig. III, whose axis 8 is journaledin the breech of the gun, and has on its inner end an arm, 9,whose studor portion 10 is engaged by a groove or guide, 11, on the breech of thegun. Journaled transversely in the breechblock is a shaft, 12, having atone end a crank, 13, (mov- 5o ing in chamber 13 of the breech block,)and having a stud or portion, 14, engaged by a groove or guide, 15, onthe breech.

Arranged centrally on shaft 12 is an arm, 16, which bears in a slot oragainst a shoulder on the firing-pin 17. (See Fig. l.) The firingpin hasthe customary spring, 18, for projecting'it, and has, further, a Sear,19, for retaining it in cocked position by bearing behind shoulder 20.The sear 19 has a spring, 21, and 6,0, trigger 22 for operating it.

It will now be observed that with the groove or guide 15 formed as shownin Fig. II the crank 13 is forced backward as the breechbiock descendswhen operated by crank 7. The 65 Shaft 12 is thereby rotated partially,and the arm 16 thereof draws back the firing pin 17 suiiiciently toallow it to be arrested by scar 19 and held in the position shown inFig. IV, when the shaft 12,' crank 13, and arm16 are returned 7o tonormal position by raising the breech-block.

Ordinarily with center-fire cartridges the parts are so arranged thatafter the firingpin is projected its point'protrudes slightly throughthe breech-block into the rear end of the barrel, so that thebreech-block cannot be removed until the tiring-pin is shifted. Toaccomplish this I arrange upon the shaft 12, on` the end opposite tocrank 13, a short arm, 23, which has preferably an elliptical form, asshown 8o in Fig. V, and is adapted to move in a chamber, 24, Fig. VI,cut out of the breech-block.

A stud, 25, on the arm 23 rests,when the parts are in the position showninFig.V, in a notch,

26, on arm 9; but as soon as thearm 9 is moved 85 in the operation oflowering the breech-block the stud 25 will be forced backward, shiftingthe arm 23 and slightly rotating the shaft 12,

so as to free the end of the ring-pin from the barrel. To preventmovement of the breechgo block while this is going on, the groove 11therein which receives the'stud 10 of the arm 9 is made concentric withthe axis 8 for a short distance.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is V 1. The combination, with agun-breech hav- A ing av groove or guide formed therein, ofay mounted inthe"breech-b1o'ck and carrying an breechfblock having a iiring-pin, ashaft arm engaging the firing-pin, and a crank on the shaft working inand operated by the said groove as the block is moved, as set forth.

2. The combination, with a breech -block having a firing-pin and a shaftfor operating the firing-pin, of a crank for moving the breechered, asset forth.

block connected thereto, so as to allow lost motion of said block onfirst moving the crank, and an arm on the firing-pin shaft engaging saidcrank and moved thereby, so that the pin will be started back before theblock is lowmoved, as described.
